CTCSS Mode (Sub-Channel) Selection The Coded Tone Controlled Squelch System (CTCSS) provides 38 Sub-Frequencies. This feature allows you to utilize the coded squelch tones (01­38) within a main channel and enables you to communicate with 15 128-6476 15 of 28 another party on the same main channel using the same subcode. (This filters out unwanted transmissions without the same coded squelch tone). To change the CTCSS Sub-channel: - From GMRS/FRS standby mode, press the MODE Button twice; a flashing oF or sub-channel number is displayed, together with the flashing CTC icon. If oF is displayed, press the Up or Down button to enable the CTCSS mode; the CTC icon will also flash on the display with the flashing sub-channel number. - Then press the Up or Down button to select the desired sub-channel for use. The CTCSS mode can be turned off by selecting the oF icon as the setting. NOTE: To communicate with other FRS units, they must be switched to the same channel and CTCSS subcode. To communicate with other FRS units that do not have subcodes, switch your unit to the same channel with the subcode set to oF. The CTCSS subcodes do not prevent others from hearing your transmission. This will only allow you to ignore all traffic on a given channel not using the same subcode. Transmit Power Selection Mode This feature permits selection of the transmitting power level to high or low on the GMRS channels. (FRS only channels 8-14 automatically operate on low power only. ) Using low power, the unit will have a lower transmit range, but battery life will be increased. NOTE: You will find that for the majority of your needs, the low-power setting will provide adequate communications on all channels; there should seldom be any need to use high power, except in situations where you need absolute maximum range. However, 16 128-6476 16 of 28 we do recommend that you not change this setting unless it proves to be necessary in your particular situation. To access the transmitter power selection function, the selected channel must be either GMRS/FRS (1-7) or GMRS only (15-22). Select the desired power as follows: - From GMRS/FRS standby mode, press the MODE Button 3 times until the Po HI or Lo indication appears with a flashing HI or LO indication on the display. NOTE: If the current channel is FRS only (8-14), power will not be selectable. - Press the Up or Down button to toggle between the High and Low selections. - Press the PTT button momentarily to confirm selection. VOX Selection Mode This option enables you to have hands-free conversation. Your voice or nearby sound is detected and the radio transmits without the need to press the PTT button. To set radio for VOX operation: - From GMRS/FRS standby mode, press the MODE button 4 times until Uo appears with the VOX icon flashing on the display.
